Make sure the glass is thick enough. For a 5 x 3 x 3 (or 150 x 90 x 90 cm) you should be using 16 mm glass. Check out this thickness calculator:

Tigerfish are brackish water species......they can live in fresh but do better kept in brackish conditions long-term, & I have read that datnoids require a higher PH & hardness than Oscars do, 7.5-8.0, & also if dats aren't kept in a high PH, they will become susceptible to disease....not sure I would recommend keeping w/ Oscars, who are strictly a FW species, & do far better in soft acidic water long-term.

THOSE WHO REFUSE KNOWLEDGE ARE DOOMED TO FAIL.

WATER CHANGES ARE THE LIFEBLOOD OF THIS HOBBY. IF YOU DON'T BELIEVE SO OR SIMPLY DON'T FEEL LIKE DOING THEM, RE-HOME YOUR FISH, SELL YOUR AQUARIUM & FIND ANOTHER HOBBY, AS YOU WILL FAIL UTTERLY, COMPLETELY, & MISERABLY.
